I'll preface with - I just barely know enough about refrigeration to be dangerous. The 608 card is all show and no go. I don't own gauges, and hope to never touch them again. Thinking about superheat and subcooling, that it comes so naturally to refer guys, gets my head spinning.
That said, the ENERGY side interests me a lot and I think I CAN get my head around that, so...
Doesn't lower pressure offer a slew of benefits, including easier serviceability and more efficient compressor operation?
If R-22 systems run lower pressures, and now mo99 can replace r-22, does this make the shift to 410a obsolete?
Will they start designing high efficiency equipment around mo99?
